[Users] t_relay and acc logging

Hello, I am struggling to make sense of acc logging when combined with forwarding a call. My openser.cfg is below this in message. Every time I place a call from a softphone that registeres to SER, I get 30+ records in acc, most of them INVITEs and some are ACKs and there are no BYEs. I can't seem to find any documentation that would explain to me what I am doing wrong. Someone, please put me on the right path. route{ setflag(3); if(method=="REGISTER") { if (!www_authorize("domain.com", "subscriber")) { www_challenge("richmedium.com", "0"); return; }; save("location"); return; } if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); return; }; if(method=="INVITE") { if (!www_authorize("richmedium.com", "subscriber")) { www_challenge("richmedium.com", "0"); return; }; } if (uri=~"^sip:1[0-9]*{10}@192.168.1.10") { forward(192.168.1.10,5061); } else { sl_send_reply("404", "Use prefix 1 to dial"); } t_relay(); }
